Product Description Product DescriptionThe DSD series ultra-high pressure electric pump is a single-outlet, high- and low-pressure pump parallel hydraulic power unit.At low pressure, the high and low pressure pumps supply oil at the same time to obtain a large output flow.At high pressure, the low pressure pump automatically returns oil at no load through the control valve,which can reduce the power consumption of the motor and reduce the heating of the oil. It has the performance of stopping to maintain pressure and single oil line inlet and return oil. Our Advantages The prestressed jack oil pump is a key piece of equipment used with prestressed jacks. Its advantages are primarily reflected in the following aspects:- Precise Pressure Control: Utilizing high-precision pressure sensors and control systems, it precisely adjusts output pressure to meet the stringent tensioning requirements of various prestressed construction applications, ensuring that prestressed tendons are properly tensioned with minimal error.- Convenient and Efficient Operation: Equipped with a user-friendly interface (such as buttons, knobs, or a CNC panel), it is easy to learn and operate. Furthermore, the adjustable oil supply speed allows for rapid completion of tensioning, pressure maintenance, and oil return processes, improving construction efficiency.- Stable and Reliable Operation: Utilizing high-quality hydraulic components (such as pumps, valves, and cylinders), it offers excellent sealing performance, minimizing problems such as oil leakage and unstable pressure. The rational overall structural design allows it to withstand complex construction site environments (such as vibration and dust), ensuring long-term, stable operation. - Outstanding Safety: Equipped with multiple safety protection devices, including overload protection (automatic shutdown when pressure exceeds the set value), overpressure relief, and leakage protection, these devices prevent accidents caused by operational errors or equipment failure, protecting construction personnel and equipment.- Highly Adaptable: Compatible with prestressing jacks of varying models and tonnages, they meet the requirements of various prestressing construction techniques, including pre-tensioning and post-tensioning methods. This wide range of applications encompasses bridge, building, and water conservancy construction.- Excellent Pressure Retention: Stable pressure retention during tensioning minimizes pressure loss, ensuring that the prestressed tendons effectively establish and maintain the designed prestress value after tensioning, thus guaranteeing the quality of the project structure.Product ParametersRated oil pressure60MpdNumber of oil nozzles2Rated displacement4 L/minOil typeNo. 46 hydraulic oilNumber of plungers2x3Fuel tank capacity42LPlunger diameterφ12mmquality130kgMotor modelY100L 2 -4Dimensions745X494X1052mmpower4 kw Revolutions1430r/min applicationxiruier Prestressing jack oil pumps are primarily used in engineering projects requiring prestressing of structures, working in conjunction with prestressing jacks to perform tensioning operations. Specific application scenarios include:- Bridge Engineering: Used for tensioning prestressing steel strands or wires during the construction of beams (such as simply supported beams and continuous beams), cable-stayed bridges, and suspension bridges, enhancing the load-bearing capacity and stability of bridge structures and reducing subsequent deformation.- Construction Engineering: Suitable for long-span floor slabs, roofs, and frame structures. By tensioning prestressed tendons, they improve the crack resistance and rigidity of components, meeting the design requirements of large-space buildings.- Water Conservancy Engineering: Used in the construction of water conservancy facilities such as sluices, aqueducts, and dams, prestressed structures are tensioned to enhance their resistance to water pressure and deformation, ensuring the safe operation of water conservancy projects.- Rail Transit Engineering: Used in the construction of prestressed components such as bridges and sleepers in railways and subways, ensuring the strength and stability of track structures to withstand the load requirements of train operation. - Geotechnical Engineering: In projects such as slope reinforcement and foundation pit support, prestressed anchor rods or cables are tensioned to enhance the stability of the rock and soil, preventing landslides, collapses, and other accidents.These applications require precise control of the tensioning force to ensure the safety and durability of the engineering structure. The stability and precise control capabilities of the prestressed jack oil pump are key to achieving this goal.CertificationsCompany ProfileGuangxi Xiruier Intelligent Technology Co., Ltd. is a high-tech enterprise integrating R&D, manufacturing, sales and service.
